Bill Bennett was pretty good too. He did a very nice job on the McLaren M19 and the first Tyrrell. Even then he was having trouble getting access to the cars as the principals were paranoid of the competition getting ahold of their secrets.

I would be happy to scan and email the cutaway illustration to Mr. Birchall, or to anyone who wishes to see it, if you send me your email address. I'm not usually too picky about copyright issues, but it seems pretty specific here.

I understand that Cosworth built around 69 SCA motors, so that those plus, Honda, Fiat, BRM, BMC, Renault and Alfa engines, all went into cars.
So that there must have been 80 or so 1 litre F2 cars built between 1964 and 1966.

I would very much like to find more of the cars. And for that matter the engines.

Anyone looking for help with a SCA try Cosworth Engineering drawing office. I was stuck for some of the fuel injection drive on the SCA in a Lotus 44 I owned. They were more than helpful. In fact they sent me drawings. The car now lives in Japan. My engine was all gear driven. The crankshaft gear was on a quill shaft. This prevented the gears from chattering.

Yes it does sound obvious
It was the first place I looked.
Several weeks after I first contacted Cosworth 'Heritage', they promised the necessary information. I tried again.
It took a month or so before I got a proper reply

They no longer have the drawings.
Then a fellow Lotus / SCA owner visited them in November 05

The drawings are not now owned by Cosworth, but by VW
As such they are currently unavailable.

To digress
I think the downfall of modern motor racing is the stultification of design.

The lower levels seem dominated by one make nonsense - no design progress there.

Even F1 has got stuck with one type of engine, and regs so tightly controlled that the designers have little scope.

Today no one could do what Brabham, Cooper, Lotus, Lola, etc did.
They built a business based on technical innovation, and as one company fell behind a new one was ready to take its place. So you had both drivers and designers striving for success. No wonder that we all prefer to look back than forward.

At the end of FIA 1 litre F2 series, a lot of the SCA engines were converted using Cosworth kits to suit the 1100cc SCCA American race series.

I understand that the drive to the ohc was changed from a train of 7 gears to part gear and part chain.Does anyone know exactly how this was done; with drawings or photos ??Kevin

I had two 1100cc injected engines for my BT28 (#103 and #106, IIRC) that were designated as SCCs. The cam drives contained no chains. Interestingly, the cutaway drawing in Post #24 doesn't seem to show the alternator on the SCC that was driven off the front of the cam.
